IMPROVEMENT IN BASIN-COCK`S.

speeieetien forming part of Lettere Patent Ne. 176,774, dated Mey 2, 1876; eppneenennied v y February 26, 1876. v

To all whom it may concern:

Be it known that I, JOHN F. GORY,plumber, of the city of New York, State of New York, have invented certain Improvements relating to Water-Gonnections for Hand-Basins, of which the following is a speciiication:

The object of the invention is to aiiord additional security against the escape ot' gas from thesewer or from the house drain-pipes.

The ordinary traps may be used in addition. The imperfect results attained by theol-dinary crooks in the pipe, designated as traps,77

' are well known, and frequently induce fevers I consider the best means of carrying out the inventiom Figure 1 is a front view with the parts inthe l position in which they are most liable to be left after the basin hasbeen used-1th at is to say,with the water turned off by the ordinary basin-cocks my apparatus having been setin such position 4that the waterl is freely discharged through the ordinary discharge-pipe connected at the bottom of the bowl. ln this condition, and also ordinarily when the bowl is left standing full, the overow-pipe is open. As it will obviously involve a liability of mischief if the overow-pipe is ever closed when the water is running, my connections are provided with three stopcocks peculiarly connected to a single handle above. The relation of these parts is such that when the water is turned on and thedischarge-pipeis closed, the overdow-pipe is certain to be open, thus enabling it to perform the function of insuring against an over-How of water from the parts being carelessly or ignorantly left in an improper l position; but when the water Iisshut oft' below by my side cocks, one of which controls the hot water and the other the cold water, then both the discharge-passage and the overflow-pipe are closed bymy central cock. In

the latter should then be closed by the basincocks above. l

It will be seen that my invention is .here

carried out by the employment of three addi- Itionalstop-cocks peculiarly related, and which are placed in the space below the wash-bowl, with a connecting-shaft leading from the central one up to a convenient point to be operated by a handle or lever. the basin-cocks, Src-may be of any ordinary or suitable character, the only dii'erence presented to the eye being the additional lever, which may be, and is represented, aslocated in the' back of the bowl between the basin-cocks. Another difference which may be presented to the eye is the absence ofl any plug to stop the oriiice at the bottom of the bowl. The central cock of my set, being turned in such position as to l.close the discharge-pipe, will perform that function effectually.

Fig. 2 is a plan view, representing the means ot operating my three cocks. The additional rigures (3, 4, and 5) represent sections on the lower plane T T.

Sections 3 and 3? belong together. They represent the water-passages open through my side cocks, controlled only by the basin-cocks above. The discharge-passage is open; the overilow is closed. This is the condition represented in Figs. l and 2, and. the one in which the parts are liable to be left during the active part ofthe day. The receipt ot' water from the pipes will be understood as being stopped oli' by the basin-cocks above.

Sections 4 and et@ belong together, and represent the parts in position tov draw water and fill the bowl-that is to say, my side cocks allow the hot and th'e cold water to liow up to the respective basin-cocks, and according as either or both the latter are open, the proper stream will dow. The discharge-passage is closed, and the overiiow-passage is open.

Figs. 5 and 5au belong together. They represent the apparatus as adjusted for the nigh t, or for any considerable period of disuse. In

The other partscases where the liability to sewer-gas is particnlarly great, the emptying of the bowl should be waited for by the operator, and the parts placed in this condition after each use at any period. In this condition the water is stopped oi' by my side cocks, and there is, therefore, no necessity for the overflow-passage being open, and my central cock is turned in such position that both the-discharge-passage and the overdowpassage are closed. In this condition of the apparat-us everything connected with the entire set of basins and connections is entirely stopped.

It will be understood that similar letters of reference indicate like parts in all the figures.

A is the bowl, and A' the ordinary marble slab which supports the bowl and the connections. B and G are the basin-cocks. The corresponding pipes b c form connections thereto fromthe street-main or from other source. (Not represented.) In addition to the ordinary basin-cock B, the pipe b may be shut off by the cock B2, having a partiallygeared wheel, Bl, irnly fixed on its upper end, and by which its positions may be controlled. The pipe c is correspondingly cut oi' by the cock U2, having firmly ixed on its upper end a partially-geared wheel, C1, by which its'position may be controlled. D is the discharge-pipe, and E the overiow. Both these pipes lead downward and connect with the central cock. The shaft M, controlled by a handle conveniently placed above the slab A', extends downward, and carries a peculiar stop-cock, M2, chambered in its interior, and provided with orifices, as denoted by further letters m1 m2, &c., which, in certain positions, open communication with the pipes D E, and with the ultimate drainpipe or connection to the sewer, marked F. The hollow 'plug M2 is providrd with two holes, m1 m2, to obtain the desired connections to the ultimate drain-pipe F, and with .one hole, m3, for the overow-pipe E, and with one hole, m4, for the discharge-pipe D. In the position shown in Figs. 3 and 32'Jv the hole m4 communicates with the discharge D, and the hole m1 communicates with the drain F. In Figs. 4 and 4' the hole m4 is turned out of connection with the discharge D, and the hole m1 out of connection with the drain F; but the hole m2 has now opened communication with the drain F, and the hole m3 is brought into connect-ion with the overflow E. In Figs. 5 and 5'Lb the discharge-passage D is closed ofi', the hole m3 is in connection with the overflow E, but the ultimate drain pipe F is entirely closed ott', and thus every connection to thesewer from which gas may arise is eifectually closed. On the shaft M, above the stop-cock M2, is a partially-geared Wheel, M1, engaging under certain conditions with the adjacent wheels Bl and C1. The cock M2 is effective in three positions. One is shown in the principal figures and in Figs. 3 and 3% When the partial gears are not en-l gaged they stand in the position plainly indicated in Fig. 2. When the cock M2 has been turned about one-fourthofa revolution, and the parts are in the positions shown in sections 4 and 4, the gearings on the other cocks are still not engaged. It will be understood that (referring to Fig. 2) the central cock M2 has been turned to the left until the teeth on this cock have commenced to have contact with the teeth of the adjacent wheel, but as yet they have communicated no motion thereto. By the further turning of the same cock M2 another quarter of a revolution to the left, the wheels Bl C1 will, by the engagement of the gears on the wheels M1 with the teeth on said wheels, have turned the latter about a fourth of a revolution, and bring the parts to the position shown in Figs. 5 and 5a. The position of the cock M2 is plainly indicated by the handle on the upper end of the shaft M, and itis hardly possible that the mostignorant or youngest member of the household can mistake; the worst result that can follow a mistake in the position is a failure to obtain Water when the cocks B and O are operated. I prefer to mount all the cocks,

B2, C2, and M2, in a single substantial casting of iron or other suitable material; but the mode of connecting the cocks, as also many of the details, may be modified within wide limits.

' 1t is very important that the connections .plug to stop the bottom of the boWlA; but

some of the advantages of the invention in other respects may be obtained by other arrangements.

I claim as my inventionv 1. 'Ihe cock or valve M2, adapted to close the discharge and overilow passages, in combinatin with a hand-basin,- and with means for simultaneously insuring the closing of the water-supply, substantially as and for the purposes herein specified. f

2. The gears or partial gears Bl Cl M', in combination with each other and with the cocks B2 G2 M2, controlling the several passages, adapted .to be operated by the single shaft M, and to not only forbid the access of water to the bowl whilev-the discharge is closed, but also to properly control the passages for the filling or emptying the bowl, or retaining the contents at' will, as and for the purposes herein specified.

In testimony whereof I have hereunto set my hand this 23d day of February, 1876, in

vthe presence of two subscribing witnesses.
